PIPE-HANGER.

Specification of Letters Patent.

Patented Dec. 31, 1912.

Application led April. 22, 1512. Serial No. 692,343.

To all whom 'it may comm.'

Be it known that we, JOHN A. HEALY and Janus H. Heim', citizens of the United States, residing at 590 Ashland avenue and 130 Kent street. respectively, in the cit T of St. Paul, county of Ramsey, and' State of Minnesota` have invented certain new and useful Improvements in Pipe-Hangers; of which the following is a specification.

This invention relates to pipe hangers` and has for its object to provide a hanger of simple structure which will etiectually support a suspended rod= bolt or pipe and at the same time will permit a reasonable amount of relative movement between the rod, bolt or pipe and the fixed object from which it is suspended. Y Y

The hanger is especi'alh7 adapted for use in suspending pipe or other objects from concrete or similar ceilings; and with this object in view the hanger consists of a member adapted to be embedded in the concrete ceiling and having a socket portion provided with a slot of peculiar configuration adapted to receive the head of a member which may be inserted therein. The first said member will be referred to throughout this specification as the fixed member and the last mentioned member as a movable member. The movable member may carry a ring lthrough which the pipe is passed or the said member ma)Y be pivotallyr connected with the upper end of a bar which turn may be provided with a ring through which the pipe is passed.

In the accompanying drawings z-Figure 1 is a side elevation of the pipe hanger embedded in a support; Fig. 2 is a similar'view taken at a right angle to Fig. 1; Fig. 3 is a .sectional view cut on the line 3 3 of Fig. 1;

Fig. -1 is a sectional view cut on the line 1 1 of Fig. 2; Fig. 5 is a sectional view cuton the line 5-,5 of Fig 1; and Fig. 6 is a detail view of a modified form of the pipe hanger.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings b v the same reference characters.

The pipe hanger includes a member 1 j which is a casting providedwith a shank '2 and a diskportion 3 The member 1 is also I provided with a socket portion l which is shaped c be eml ceiling provided in its lower side with a T slot 5. The member 1 1s adapted to bedded in concrete which forms the of a building or other object and the said member is provided at the sides of its socketed portion l with spaced lugs 6 the lower surfaces of which are adapted to remain tiush with the surface ofthe ceiling and in these lugs. nails., screws or bolts may be placed, whereby the member =1 is fastened at the ceiling of the structure until the con? crete shall have set. The hanger also includes a member T which is provided with a head 8, tapped for pipe. bolt or rod, the said head beingapprosimately. square in transverse section with :its under portion rounded as at 9. As shown in Eig.1of the lower end with a ring 10. tappedfor pipe,

at 11 may be passed. As shown in Fig. 6 oi the drawing, the member T is provided at socket only when the axis of the body portion of the member 7 is at an lacute angle to the plane of the lower edge of theA slot Thus when the said head is inserted in the slot and the bod v -portion of the member 't' hangs vertically or substantially at a rightr angle to the plane of the lower edge of the i slot 5 it is impossible for the member to become detached from the member 1. At the same time the member T at its lower portion will have a certain amount of swineing movement in any horizontal direction so thatthe pipe supported by the member may be moved slightly withoutdisconnecting the member 'T from the member 1. This is to allow for contraction and expansion of the pipe and `also permits of moving the same during repairs or at the time of the installation of the pipe sistem. At the same time it permits that the member 1 may be embedded in the concrete approximately atits proper position and if it is embedded at a proper position and during the time that the concrete solidiiied should it. move or assume a slightly slanting position it will I still perform its function in eiectually holddrawing, the member T is progided at its` bolt or rod through whicha pipe indicated sible to slip the said head into the said to woodwork and thus supported in position i its lower end with spaced ears 12. v'The member 1 it is necessary to remove' the pipev section 11 from the member 7, then swing the member 7 into such position that the head 8 of the said member may pass edgewise through the apertures of the T shaped slot- 5 and in order to do this it is necessary to swing the body portion of the member 7 into the stem portion of the slot There fore the T shaped slot 5 by reason of its configuration plays an important part in combination with the parts of the pendent member 7 as shown and described.

The upper end of the member 7 is screw threaded and is tapped into the head 8. Therefore when it is desired to remove the member 7 from the head 8 withoutl detaching the said head from the socket portion 4, a wedge may be inserted in the slot 5 which will hold the head 8 against rotation and then by applying a -wrench to the rod 7 the said rod may be unscrewed from the head` In a similar manner the rod 7 may be assembled with the head 8;

Having thus described the invention, what is claimed as new is:

1. A. hanger comprising a member provided with a socket portlon having in its lower side a T-shaped slotl which is completely inclosed between the 'vertical walls of the socket portion, said slot having all portions of the upper edges of the walls of the slot lying in the same plane, and a pendant member having a head approximately Loaaoee lsquare with a rounded under side, said ing a pipe. 2. A pipe hanger comprising a member provided with a socketed portion having a 'l' shaped slot, a pendent member having a head which is approximately square in transverse section and provided with a rounded under side, said head adapted to be received within-the slot of the socketed member when the body poriion of the pendent member is disposed at an acute angle to the plane of the edge of the slot, said socketed member adapt-ed to retain the said pendent member when the axis of the body portion of the pendent member is approximately vertical with the plane of the slot, the parts being So proportioned that the pendent member may have slight swinging movement while coniined with relation to the socketed member, and a ring carried by the pendent member for supporting a pipe section.

3. A pipe hanger comprising a member having a socketed portion provided with a T shaped slot, a pendent member having a head approximately square in transverse section and provided with a rounded under side, said head adapted to be-slipped into the slot by edgewise movement through the apertures thereof, said pendentmember having at its lower end spaced ears, a bar connected at one end between said ears, and a ring carried at the lower end of the bar and adapted to receive a pipe section.
